Nettet2. For the Integral: ∫ sin ( a x) , it is fairly simple to take the Laplace transform of the absolute value of sine, treating it as a periodic function. L ( sin ( a x) ) = ∫ 0 π a e − s t sin ( a x) 1 − e − π s a = a ( 1 + e − π s a) ( a 2 + s 2) ( 1 − e − π s a) Then the integral of the absolute value would simply be ... Nettetthe left side, the intervals on which f(x) is negative give a negative value to the integral, and these “negative” areas lower the overall value of the integral; on the right the integrand has been changed so that it is always positive, which makes the integral larger.

NettetHence the integral ∫∞a sin ( x) x dx exists for every a ∈ R +. Hence we can write ∫a 0sinc(x / π)dx + ∫∞ a sin(x) x dx = ∫a 0sinc(x / π)dx + ∫∞ asinc(x / π)dx = ∫∞ 0sinc(x / π)dx . Now all terms on the left hand side exist. Hence also the right hand side. Then we analyze the existence of the respective Lebesgue integral.
